Hofmann’s tinkering led him to create Byte, an impressively ambitious mobile app for iPhone that enters a private beta today. (It’s scheduled to open to the public later in July; an Android version is coming later this year.) Byte is a creative tool and a social network. Mostly, though, it’s a playground: if Vine encourages creativity by giving you constraints, Byte aims to destroy the notion of constraints and see what emerges from the chaos.
